[0062] Specifically, the tool moving device includes a first Y-axis linear module 6-6, the first Y-axis linear module 6-6 is fixedly arranged on the fixed platen 6-1, the first Y-axis linear module 6-6 is provided with a first X-axis linear module 6-7, the first X-axis linear module 6-7 is provided with a tool extension column 6-8, and the first tool 6-9 is fixedly arranged on the tool extension column 6-8. The first Y-axis linear module 6-6 is used to drive the first X-axis linear module 6-7 to move along the Y-axis direction, the first X-axis linear module 6-7 is used to drive the tool extension column 6-8 to move along the X-axis direction, and the tool extension column 6-8 is arranged in a horizontal direction. The first tool 6-9 can move along the X-axis and Y-axis directions by using the first Y-axis linear module and the first X-axis linear module in combination.

[0063] The rotary chuck 6-2 is connected to the rotary chuck drive motor 6-13 and is driven to rotate by the rotary chuck drive motor 6-13. The rotary chuck drive motor 6-13 is fixedly arranged at the lower end of the fixed platen 6-1, and the rotary chuck 6-2 is located above the fixed platen 6-1. In the present embodiment, the rotary chuck 6-2 is a three-jaw chuck, which clamps the workpiece in an inner clamping manner. When clamping, the claws on the three-jaw chuck are in tight contact with the outer cavity side wall 9-6 on the blade 9, and the blade 9 is placed horizontally in the clamped state. The first tool 6-9 is moved to perform chip processing on the hub end face 9-2 and the blade end face 9-4 of the blade 9, thereby realizing the first processing procedure of the blade 9.

[0064] The transfer chuck 6-4 is installed on the transfer drive device, and the transfer drive device drives the transfer chuck 6-4 to move along the X-axis and Y-axis directions; the transfer chuck 6-4 is connected to the transfer chuck 6-4 drive motor, and the transfer chuck 6-4 drive motor drives the transfer chuck 6-4 to rotate; when the transfer chuck 6-4 clamps the fan blade 9, the outer cavity on the fan blade 9 faces downward; the second tool 6-10 extends into the outer cavity and processes the outer end surface 9-7 of the outer cavity, the inner end surface 9-8 of the outer cavity and the side wall 9-6 of the outer cavity.

[0065] The transfer drive device includes a second X-axis linear module 6-11, a second Y-axis linear module 6-12 is provided on the second X-axis linear module 6-11, and a transfer chuck 6-4 drive motor is provided on the second Y-axis linear module 6-12. The transfer chuck 6-4 drive motor drives the transfer chuck 6-4 to rotate on a horizontal plane. Through the coordinated use of the second X-axis linear module 6-11 and the second Y-axis linear module 6-12, the transfer chuck 6-4 can move along the X-axis and Y-axis directions. The second X-axis linear module is provided on the fixed table 6-1.

[0066] The transfer chuck 6 - 4 can be a three-jaw chuck. The transfer chuck 6 - 4 clamps the fan blade 9 in an external clamping manner. During clamping, the clamping claws on the transfer chuck 6 - 4 contact the outer side of the hub 9 - 1 of the fan blade 9 .

[0067] By moving the transfer chuck 6-4 in the X-axis direction, the fan blade 9 can be transferred between different processing stations. That is to say, when the fan blade 9 is processed at the station where the rotating chuck 6-2 is located, the fan blade 9 can be transferred to the station where the second tool 6-10 is located by moving the transfer chuck 6-4 and perform the second processing step; when the fan blade 9 is processed at the station where the second tool 6-10 is located, the fan blade 9 is transferred to the station where the fixed chuck 6-5 is located by the transfer chuck 6-4 and perform the third processing step.

[0068] At the same time, the rotating chuck 6-2 can rotate under the drive of the transfer chuck 6-4 driving motor and can move along the Y-axis direction. Through the above two modes of movement and in cooperation with the second tool 6-10, the outer cavity side wall 9-6, the outer cavity outer end surface 9-7, and the outer cavity inner end surface 9-8 can be processed to achieve the second processing step of the fan blade 9. In other words, the transfer chuck 6-4 not only has the function of transferring the workpiece, but also the transfer chuck 6-4 itself is also a part of the second processing step, and cooperates with the second tool 6-10 to complete the processing task of the fan blade 9.

[0069] The fixed chuck 6-5 is arranged on the fixed table 6-1. At least three claws are arranged on the fixed chuck 6-5, and the third tool 6-18 is located between the claws. The third tool 6-18 is installed on the third Y-axis linear module 6-14, and the third tool 6-18 is driven to move along the Y-axis by the third Y-axis linear module 6-14. The third Y-axis linear module 6-14 is provided with a tool driving motor 6-15 for driving the third tool 6-18 to rotate; when the fixed chuck 6-5 clamps the fan blade 9, the inner cavity on the fan blade 9 faces downward; the third tool 6-18 extends into the inner cavity and processes the inner cavity side wall 9-9.

[0070] Among them, the claws on the fixed chuck 6-5 can move along the radial direction of the fixed chuck 6-5, and the fixed chuck 6-5 clamps the fan blade 9 by an external clamping method. When clamping, the chuck on the fixed chuck 6-5 presses against the outer surface of the hub 9-1 of the fan blade 9.

[0071] The tool drive motor 6-15 is connected with a rotating shaft 6-16, which is coaxially arranged with the fixed chuck 6-5. The third tool 6-18 is connected to the upper end of the rotating shaft 6-16. The third Y-axis linear module is provided with a bearing seat 6-17, through which the rotating shaft 6-16 passes and rotates with the bearing seat 6-17. The rotating shaft 6-16 is arranged along the Y-axis direction, and the rotating shaft 6-16 is supported by the bearing seat 6-17 to ensure the stability of the rotating shaft 6-16 when rotating.

[0072] In this embodiment, the third tool 6-18 can be an eccentric boring tool. The third tool 6-18 is connected to the upper end of the rotating shaft 6-16, and the third tool 6-18 is driven to rotate by the tool driving motor 6-15 to realize the main movement of the third tool 6-18, and the third tool 6-18 is driven to move along the Y-axis direction by the third Y-axis linear module 6-14 to realize the feeding movement of the third tool 6-18.

[0073] It is worth mentioning that during the machining process, the fixed chuck 5 does not rotate, and the cutting process of the side wall of the inner cavity is achieved by the rotation of the third tool 18 .

[0074] The loading robot 4 is used to transfer the fan blades 9 on the loading conveyor belt 1 to the rotating chuck 6-2, thereby realizing the automatic loading process.

[0075] The unloading conveyor belt 2 is arranged on one side of the loading conveyor belt 1, and the unloading conveyor belt 2 is arranged parallel to the loading conveyor belt 1. The unloading manipulator 7 is used to transfer the fan blades 9 after processing to the unloading conveyor belt 2 to realize the automatic unloading process. The unloading manipulator is provided with an unloading clamp 7-1 for grabbing the fan blades.

[0076] Furthermore, a loading positioning component 5 is provided between the loading conveyor belt 1 and the processing unit, and the loading positioning component 5 includes a fixed platform 5-1 and a positioning claw plate 5-2 provided on the fixed platform 5-1, and the positioning claw plate 5-2 is provided with at least three positioning claws that can move radially along the positioning claw plate 5-2. A suction cup 4-1 is provided on the loading manipulator 4, and the loading manipulator 4 grabs the fan blade 9 through the suction cup 4-1, and the suction cup 4-1 is adsorbed on the hub end face 9-2 of the fan blade 9. When the loading robot 4 is loading the fan blade 9, the loading robot 4 first grabs the fan blade 9 from the loading conveyor belt 1 and places it on the positioning claw plate 5-2, and then the loading robot 4 releases the fan blade 9, and the positioning claws on the positioning claw plate 5-2 clamp the fan blade 9, and at this time the positioning claws are in contact with the side wall of the outer cavity on the fan blade 9; then the loading robot 4 grabs the fan blade 9 again through the suction cup 4-1, and then the positioning claw plate 5-2 releases the fan blade 9, and the loading robot 4 transfers the fan blade 9 to the rotating chuck 6-2.

[0077] Among them, the positioning claw plate 5-2 clamps the fan blade 9 in an internal clamping manner, and during clamping, the positioning claw contacts the side wall of the outer cavity on the fan blade 9 and realizes the positioning of the fan blade 9. During the process of the feeding robot 4 feeding the fan blade 9, the fan blade 9 is placed on the positioning claw plate 5-2 for clamping and positioning, and then re-grasped by the suction cup 4-1. In this way, the grasping position of the feeding robot 4 on the fan blade 9 can be kept consistent each time, thereby ensuring the consistency of the feeding of the fan blade 9.

[0078] An automatic sheathing device 8 is provided between the processing unit and the unloading conveyor belt 2. The automatic sheathing device 8 comprises an upper sheath manipulator 8-1 and a sheath discharging device 8-2. The upper sheath manipulator 8-1 is provided with a sheath clamping claw 8-1-1 for grabbing the sheath 11. When the sheath clamping claw 8-1-1 grabs the sheath 11, the sheath clamping claw 8-1-1 clamps the outer side of the sheath 11. The upper sheath manipulator 8-1 grabs the sheath 11 from the sheath discharging device 8-2 and puts the sheath 11 on the core shaft 9-5 of the fan blade 9.

[0079] Since the mandrel 9-5 on the fan blade 9 is a component that cooperates with the motor, the mandrel 9-5 should not be bumped or scratched during the production process. In actual process, the mandrel 9-5 is easy to bump or scratch with other objects during the production process, causing the mandrel 9-5 to be damaged. If the damage is serious, the entire fan blade 9 will be scrapped. The present invention fully considers the problem that the mandrel 9-5 is easily damaged. After the fan blade 9 is processed, the sheath 11 is put on the end of the mandrel 9-5 by the automatic sheathing device 8. The sheath 11 is wrapped around the mandrel 9-5, which plays a good protective role on the mandrel 9-5. This ensures that the mandrel 9-5 on the fan blade 9 will not be bumped or scratched during the subsequent circulation and assembly process; when the fan blade 9 is assembled, it only needs to remove the sheath 11 from the mandrel 9-5. The sheath 11 can be reused.

[0080] Wherein, the structure of the sheath 11 is as follows Fig.12 As shown, the sheath 11 is cylindrical in shape and made of rubber, which has good cushioning properties. The inner diameter of the sheath 11 is slightly smaller than the diameter of the mandrel 9-5, so that after the sheath 11 is sleeved on the mandrel 9-5, it can maintain a certain interference fit with the mandrel 9-5, ensuring that the sheath 11 can be stably sleeved on the mandrel 9-5.

[0081] Specifically, the sheath discharging device 8-2 includes a vibrating disk 8-2-1, on which a discharging guide rail 8-2-2 is provided, and at one end of the discharging guide rail 8-2-2 away from the vibrating disk 8-2-1, a material control component 8-2-3 is provided, on which a material waiting hole 8-2-6 is provided, and on which a material pushing cylinder 8-2-4 is provided, and on which a material pushing rod 8-2-9 is connected, the material pushing cylinder 8-2-4 drives the material pushing rod 8-2-9 to move so as to realize the tightening or loosening of the sheath 11 in the material waiting hole 8-2-6.

[0082] A movable limit plate 8-2-8 is provided in front of the material waiting hole 8-2-6, and the movable limit plate 8-2-8 is connected to the lifting drive cylinder 8-2-7, and the movable limit plate 8-2-8 is driven by the lifting drive cylinder 8-2-7 to move up and down; the horizontal distance between the movable limit plate 8-2-8 and the ejector rod 8-2-9 is less than the length of the sheath 11. Side baffles 8-2-5 are respectively provided on both sides of the material control component 8-2-3.

[0083] The width of the discharge guide rail 8-2-2 can only allow the sleeves 11 to pass through one by one. There is a gap of a certain width between the movable limit plate 8-2-8 and the material control component 8-2-3, so that when one end of the sleeve 11 is against the movable limit plate 8-2-8, a part of the sleeve 11 is extended out of the material waiting hole 8-2-6, and the extended part is convenient for the sleeve clamping claw 8-1-1 on the upper sleeve manipulator 8-1 to clamp. The horizontal distance between the movable limit plate 8-2-8 and the ejector rod 8-2-9 is less than the length of the sleeve 11, so that it can ensure that while one end of the sleeve 11 is in contact with the movable limit plate 8-2-8, the sleeve 11 can also be in contact with the ejector rod 8-2-9 and be tightened by the ejector rod 8-2-9.

[0084] The specific method of the upper sheath manipulator 8-1 grabbing the sheath 11 from the sheath discharging device 8-2 is as follows:

[0085] The sheath 11 is discharged one by one along the discharge guide rail 8-2-2, and the sheath 11 at the front end enters the material waiting hole 8-2-6. One end of the sheath 11 extends out of the material waiting hole 8-2-6 and contacts the movable limit plate 8-2-8 in the ascending state, and the ejector rod 8-2-9 pushes the sheath 11 in the material waiting hole 8-2-6 tightly.

[0086] When the upper sheath manipulator 8-1 grabs the sheath 11, the lifting drive cylinder 8-2-7 drives the movable limit plate 8-2-8 to move to the lowered state, and the upper sheath manipulator 8-1 clamps the part of the sheath 11 at the front end extending out of the material waiting hole 8-2-6 through the sheath clamping claw 8-1-1, and the ejecting rod 8-2-9 releases the sheath 11, and the sheath 11 is removed by the upper sheath manipulator 8-1;

[0087] After the sleeve 11 is removed, the lifting drive cylinder 8-2-7 drives the movable limit plate 8-2-8 to move to the rising state, and the next sleeve 11 moves into the waiting hole 8-2-6 until one end contacts the movable limit plate 8-2-8, and then the ejector rod 8-2-9 pushes the sleeve 11 currently located in the waiting hole 8-2-6 tightly and waits for the next grabbing by the upper sleeve manipulator 8-1.

[0088] A workpiece pallet 3 for carrying the fan blades 9 is placed on the loading conveyor belt 1 and the unloading conveyor belt 2, and a workpiece pallet moving manipulator 10 is provided between the loading conveyor belt 1 and the unloading conveyor belt 2; when all the fan blades 9 on the workpiece pallet 3 at the front end of the loading conveyor belt 1 are removed, the workpiece pallet moving manipulator 10 transfers the workpiece pallet 3 to the front end of the unloading conveyor belt 2. The front end of the loading conveyor belt 1 refers to the end of the loading conveyor belt 1 close to the processing unit, and the front end of the unloading conveyor belt 2 refers to the end of the unloading conveyor belt 2 close to the processing unit.

[0089] The workpiece pallet 3 is provided with a plurality of placement holes for placing the fan blades 9. When all the fan blades 9 on the workpiece pallet 3 at the front end of the loading conveyor belt 1 are removed, the workpiece pallet moving manipulator 10 transfers the empty workpiece pallet 3 to the front end of the unloading conveyor belt 2 to receive the fan blades 9 transferred by the unloading manipulator 7 and completed processing.

[0090] A fan blade processing method comprises the following specific steps:

[0091] Step 1: The loading robot 4 grabs the fan blade 9 from the loading conveyor belt 1 and places the fan blade 9 on the positioning claw plate 5-2, then the loading robot 4 releases the fan blade 9, and the positioning claw on the positioning claw plate 5-2 clamps the fan blade 9, at which time the positioning claw contacts the side wall of the outer cavity on the fan blade 9; then the loading robot 4 grabs the fan blade 9 again through the suction cup 4-1, and then the positioning claw plate 5-2 releases the fan blade 9, and the loading robot 4 transfers the fan blade 9 to the rotating chuck 6-2.

[0092] Step 2: Rotate the chuck 6-2 to clamp the blade 9. At this time, the hub end face 9-2 on the blade 9 faces upward. The rotating chuck 6-2 drives the blade 9 to rotate, and the hub end face 9-2 and the blade end face 9-4 on the blade 9 are processed by the first tool 6-9. After the processing is completed, the rotating chuck 6-2 stops rotating.

[0093] Step three: Rotate the chuck 6-2 to loosen the fan blade 9, move the transfer chuck 6-4 to the top of the fan blade 9 and clamp the fan blade 9, and then use the transfer chuck 6-4 to move the fan blade 9 to the top of the second tool 6-10; then the transfer chuck 6-4 rotates and moves downward, and the second tool 6-10 extends into the outer cavity on the fan blade 9 and processes the outer cavity side wall 9-6, the outer end face 9-7, and the inner end face 9-8 of the outer cavity; after the processing is completed, the transfer chuck 6-4 stops rotating.

[0094] Step four: The transfer chuck 6-4 moves the fan blade 9 to the fixed chuck 6-5 and loosens the fan blade 9. The fixed chuck 6-5 clamps the fan blade 9. At this time, the inner cavity on the fan blade 9 faces downward; the tool drive motor 6-15 drives the third tool 6-18 to rotate, and drives the third tool 6-18 to move upward through the third Y-axis linear module. The third tool 6-18 extends into the inner cavity and processes the side wall 9-9 of the inner cavity; after the processing is completed, the third tool 6-18 stops rotating and withdraws from the inner cavity.

[0095] Step 5: The fixed chuck 6-5 loosens the fan blade 9, the unloading manipulator 7 grabs the fan blade 9 from the fixed chuck 6-5 and moves the fan blade 9 to the upper sheath 11 position, and the upper sheath manipulator 8-1 grabs the sheath 11 from the sheath discharging device 8-2 and puts the sheath 11 on the core shaft 9-5 of the fan blade 9; wherein, the specific method of the upper sheath manipulator 8-1 grabbing the sheath 11 from the sheath discharging device 8-2 is as follows:

[0096] The sheath 11 is discharged one by one along the discharge guide rail 8-2-2, and the sheath 11 at the front end enters the material waiting hole 8-2-6. One end of the sheath 11 extends out of the material waiting hole 8-2-6 and contacts the movable limit plate 8-2-8 in the ascending state, and the ejector rod 8-2-9 pushes the sheath 11 in the material waiting hole 8-2-6 tightly.

[0097] When the upper sheath manipulator 8-1 grabs the sheath 11, the lifting drive cylinder 8-2-7 drives the movable limit plate 8-2-8 to move to the lowered state, and the upper sheath manipulator 8-1 clamps the part of the sheath 11 at the front end extending out of the material waiting hole 8-2-6 through the sheath clamping claw 8-1-1, and the ejecting rod 8-2-9 releases the sheath 11, and the sheath 11 is removed by the upper sheath manipulator 8-1;

[0098] After the sheath 11 is removed, the lifting drive cylinder 8-2-7 drives the movable limit plate 8-2-8 to move to the rising state, and the next sheath 11 moves into the material-waiting hole 8-2-6 until one end contacts the movable limit plate 8-2-8, and then the ejector rod 8-2-9 pushes the sheath 11 currently located in the material-waiting hole 8-2-6 tightly and waits for the next grabbing by the upper sheath manipulator 8-1;

[0099] Then the unloading robot 7 transfers the fan blade 9 to the unloading conveyor belt 2.

[0100] It is worth mentioning that when the fan blade 9 moves to the upper sleeve 11 position, the fan blade 9 is located above the upper sleeve manipulator 8-1, and the core shaft 9-5 on the fan blade 9 is vertically downward. After the upper sleeve manipulator 8-1 grabs the sleeve 11, it puts the sleeve 11 onto the core shaft 9-5 from bottom to top.

[0101] The present invention has the following advantages:

[0102] 1. The present invention can automatically complete the processing of the hub end face 9-2, the blade end face 9-4, the outer cavity side wall 9-6, the outer cavity outer end face 9-7, the outer cavity inner end face 9-8, and the inner cavity side wall 9-9 of the fan blade 9, and realize the automatic loading and unloading process of the fan blade 9. The entire processing process does not require human participation, which greatly improves the processing efficiency and reduces labor costs.

[0103] 2. After completing the processing of each processing surface on the fan blade 9, the present invention uses the automatic sleeve device 8 to cover the sleeve 11 on the core shaft 9-5 of the fan blade 9, thereby protecting the core shaft 9-5 of the fan blade 9 and ensuring that the core shaft 9-5 on the fan blade 9 will not be bumped or scratched during the subsequent circulation and assembly process.

[0104] The present invention is not limited to the above-mentioned optimal implementation mode. Anyone can derive other various forms of products under the inspiration of the present invention. However, no matter what changes are made in the shape or structure, all technical solutions that are the same or similar to those of the present application fall within the protection scope of the present invention.
